DNA polyanions trapped in a mass spectrometer undergo electron detachment following UV irradiation. Photodetachment is a single-photon process. Its efficiency depends on the nature of the DNA bases, the ion's charge, and the excitation wavelength. Photodetachment can therefore be used to perform ion spectroscopy experiments, which probe electronic excitation within the initial charge state of the nucleic acids. Ion spectroscopy experiments on trapped nucleic acid cations and anions were performed from 4 to 20 eV using an OPO laser or using synchrotron radiation. Photoelectron spectroscopy experiments were also performed on multiply charged anions to probe direct detachment cross sections and electronic excitations within the final charge. The electronic spectra obtained from photodetachment integral cross sections show several resonances, provided that the photon energy is larger than the electron binding energy. We will also discuss whether the electronic spectra obtained via photodetachment can be used to probe gas phase ion structure. [less ▲]

An ensemble smoother scheme is presented to assimilate HF radar surface currents to improve tidal boundary conditions and wind forcings of a circulation model of the German Bight. To create an ensemble of dynamically realistic tidal boundary conditions, a cost function is formulated which is directly related to the probability of each perturbation. This cost function ensures that the perturbations are spatially smooth and that the structure of the perturbations satisfies approximately the harmonic linearized shallow water equations. Based on those perturbations an ensemble simulation is carried out using the full three-dimensional General Estuarine Ocean Model (GETM). Optimized boundary values are obtained using all observations within the assimilation period using the covariances of the ensemble simulation. The approach acts like a smoother scheme since all observations are taken into account. Since the scheme aims to derive the optimal perturbation, it might be called Ensemble Perturbation Smoother. The final analysis is obtained by rerunning the model using the optimal perturbation to the boundary conditions. The analyzed model solution satisfies thus the model equations exactly and does not suffer from spurious adjustments often observed with sequential assimilation schemes. Model results are also compared to independent tide gage data. The assimilation did also reduce the model error compared to those sea level observations. The same scheme has also been used to correct surface winds. Surface winds are crucial for accurately modeling the marine circulation in coastal waters. The method is validated directly by comparing the analyzed wind speed to in situ measurements and indirectly by assessing the impact of the corrected winds on sea surface temperature (SST) relative to satellite SST.

Context: Deficient HRH management – especially insufficient training and motivation, and adverse distribution of qualified staff countrywide, at the expense of poor and remote areas – has been identified for over a decade as one major constraint for the implementation of Mali's national health policy. Main objective: The HRH policy aims to define a coherent framework for the ministry of health (MoH) and its partners in order to ensure the harmonious development, distribution, management and motivation of health staff so as to ultimately improve health results. The policy is translated into an operational plan dealing specifically with training, recruitment, motivation, and career management. Methodology: The HRH policy and plan were developed by a core team under the leadership of the Planning Department of the MoH, with the involvement from other departments of the MoH, the ministries in charge of finance (MoF) and civil service (MoCS), and donors. After analyzing existing studies and data, the diagnosis over the major problems to be tackled was done. This allowed identifying the main orientations of the policy, which were then translated into strategies and interventions, and then costed. Once the policy and plan have been drafted by the core team, they have been circulated to all departments and partners and discussed in several meetings with different stakeholders at central level. After integrating comments from these meetings, the MoH organized a validation workshop with very broad participation (including the operational level, private sector, and civil society) so as to ensure ownership. Final amendments were negotiated with the MoF and MoCS in order to be adopted as a national policy by the Counsel of Ministers by the end of 2009. Results: The HRH policy and plan now benefit from wide political support by major stakeholders. Yet, implementation still has been delayed because of the management modalities at operational level still need to be definitively agreed upon. Conclusion: The inclusive development process has been necessary to move on with the complex and highly sensitive issue of HRH management, and to get the support from MoF, MoSC and donors who are supposed to contribute to its financing.

Stress intensity factors (SIFs) computation techniques based on J-integral methods [1] are widely used in finite element codes. However, the Displacement Extrapolation Method (DEM) [2] is an alternative way to compute them. The idea is to process an extrapolation based on the relative displacement of the crack face nodes. This method is generally less accurate than integral methods, but it requires much less computational resources. The method is well documented and is implemented in some finite element software. The X-FEM introduced in [3] is suited for crack problems. However, the literature on DEM in the X-FEM case seems to be non-existent in the present time. This paper tries to fill this lack in the literature by describing a new method using X-FEM. The approach followed here is only developed for Linear Elastic Fracture Mechanics. Note that the finite element software Code_Aster [4] already computes SIFs with DEM in X-FEM, but in a slightly different way. [less ▲]

Substructured and layered thin sheets can be found in a variety of structural, e.g. structured panels, as well as high-tech applications. A typical example is flexible electronics, e.g. flexible displays, where layers of different materials and interconnects are stacked to provide the necessary functionality. The resulting complex three dimensional geometry of the structured thin sheets in this type of applications prohibits the use of classical layer-wise composite shell theory. For these problems, a computational homogenization technique for thin structured sheets is proposed in this work, based on the computational homogenization concepts previously developed for the first- and second-order continua.

La vie en société de milliers d’individus apparentés dans un milieu confiné augmente le risque de transmission des pathogènes. Par le biais de comportements hygiéniques collectifs tels quel le rejet des déchets, les insectes sociaux ont développé des défenses spécifiques contre les pathogènes. Nous avons comparé la dynamique de rejet de différents types de déchets (cadavres, proies et morceaux de vermiculite) introduits dans des nids de Myrmica rubra. L’analyse vidéo, réalisée grâce à un programme original de suivi du déchet et de digitalisation des zones de couvain, a permis un suivi précis du déplacement de ces déchets au sein du nid. La vermiculite a été rapidement rejetée après 12 ± 4 minutes, les cadavres ont été éliminés après 139 ± 28 min et les proies ont été consommées puis rejetées après 17,3 ± 0,3 heures. L’analyse spatiale des déchets a montré un déplacement rapide des cadavres loin du couvain alors que les proies étaient fréquemment apportées près des larves pour la consommation. L’efficacité de la gestion des déchets a été testée par ailleurs en comparant la survie de colonies de fourmis ayant ou non la possibilité de rejeter leurs cadavres. La mortalité des adultes et des larves vivant dans des nids contraints de garder leurs cadavres est significativement supérieure à celle observée dans les colonies contrôles, confirmant l’importance de ce rejet pour la survie et le bon état sanitaire de la fourmilière.

Since 1990s Vietnam is undergoing rapid industrialization with the national goal of becoming an industrial country. As a result, large tracts of agricultural land were conversed to industrial zones and clusters. This paper analyzes the complex impacts caused by industrialization on household food security. Both qualitative and quantitative methods were applied to investigate how land conversion process to industrial companies affected food security of different groups of peasant households in Hung Yen province, the most rapid industrialization province in Red River Delta of Vietnam. The study showed that industrialization and neo-liberalism affected household food security in three aspects: the lost of large agricultural land area which did not ensure stable jobs for peasants; the decline of living quality as a result of environmental pollution and high living costs; and the lost of household self reliance on food, with 77 percent of surveyed households not producing enough food for their own consumption. Industrialization had created a new class structure in the Vietnamese countryside with the rise of landless peasants who survived by selling their labor and who are net food buyers. The study contributes to the research that link the analysis of household food security with livelihood systems in the processes interacting across scales, from the very local to the global.

In the first part of this presentation it will be shown how the general linear model is used to describe experimental functional magnetic resonance imaging (fMRI) data from one subject. Functional magnetic resonance imaging is a neuroimaging method which is used to study the human brain and its functional areas. Based on the general linear model, optimal designs for one-subject fMRI experiments can be obtained by application of the D- and A-optimality criterion. Because of the huge design space for fMRI experiments, a genetic algorithm (GA) is employed to find optimal designs for fMRI experiments based on a multi-objective design criterion. The second part of the presentation will focus on the application of mixed effects models in analysis of fMRI experiments from multiple subjects. Optimal designs for multi-subject experiments are considered and the optimal combination of number of subjects and fMRI scanner time/imaging time per subject will be studied with respect to a linear cost function.

During the last decade large efforts have been devoted to the development of high-resolution schemes to solve advection problems. High-resolution conservative numerical schemes satisfying conservative, monotonicity preserving and shock-capturing properties are nowadays widely used in ocean modeling. Among these, TVD schemes, based on the concept of Total Variation Diminishing (TVD), were progressively adopted because of their good behavior that guarantees a solution free from numerical artifacts (no overshooting, no spurious oscillation, small diffusion) that can spoil the physical significance of the results. Most of the TVD schemes and associated limiters have been originally developed in idealized one-dimensional flows described by a linear advection. In finite volume marine models, one has however often to deal with the depth integrated advection equation. This formulation is usually preferred because of its conservative form that is particularly suited to numerical treatment using a finite volume approach. Conservative numerical schemes can be easily formulated to ensure that the total mass of the advected quantity is conserved. This property is very valuable in the context of environmental studies for which a strict equilibrium of the mass budget of pollutants is often more relevant that the raw accuracy of the integration scheme. In the same context, the numerical scheme should also produce neither new local extremum nor negative concentrations, i.e. it should be monotonicity preserving which is implied by the TVD property. The development of TVD schemes for the resolution of advection equations written in the conservative form is however not trivial. Numerical experiments show that the blind application to the depth-integrated equation of the usual TVD schemes and associated flux limiters introduced in the context of linear advection can lead to non-TVD solutions in presence of complex geometries. Spatial and/or temporal variations of the local bathymetry can indeed break the TVD property of the usual schemes. Really TVD schemes can be recovered by taking into account the local depth and its variations in the formulation of the flux limiters. Using this approach, a generalized superbee limiter is introduced and validated. [less ▲]

Numerical ocean models are affected by errors of various origins: errors in the initial conditions, boundary conditions and atmospheric forcings, uncertainties in the turbulence parametrization and discretization errors. In data assimilation, observations are used to reduce the uncertainty in the model solution. Ensemble-based assimilation schemes are often implemented such that the expected error of the model solution is minimized. It is shown that the observations can also be used to obtain improved estimates of the, in general, poorly known boundary conditions and atmospheric forcings. An ensemble smoother scheme is presented to assimilate high-frequency (HF) radar surface currents to improve tidal boundary conditions and wind forcings of a circulation model of the German Bight. To create an ensemble of dynamically realistic tidal boundary conditions, a cost function is formulated which is directly related to the probability of each perturbation. This cost function ensures that the perturbations are spatially smooth and that the structure of the perturbations satisfies approximately the harmonic linearized shallow water equations. Based on those perturbations an ensemble simulation is carried out using the full three-dimensional General Estuarine Ocean Model (GETM). Optimized boundary values are obtained using all observations within the assimilation period using the covariances of the ensemble simulation.

Due to the high variability inherent of experimental recipients, validating biological methods is often a complex exercise, and following ICH Q2R1 recommendations is not always feasible and/or meaningful. Linking systematic error and random error to obtain a unique criterion, as defined in ISO guideline, could be of interest to capture the total variability in biological assays. In this paper, the use of Total Error concept in the validation of biological assays was for the first time investigated and compared to a conventional interpretation of the ICH guideline. Both decision methodologies concluded that the assaywas valid from 2.13 to 5.83 log10(CCID50/ml). However, only the Total Error approach using accuracy profile as decision tool allowed to guarantee that accurate and reliable results will be obtained during the future routine application of the assay. In addition, the risk to obtain out of acceptance limits results was estimated using this approach and was found out to be at the most 3.1% irrespective of the concentration level, thus demonstrating the reliability of the biological assay.

Objectives: The objective is to analyze the content of the Paris Declaration (PD) on aid effectiveness and Accra Agenda for Action (AAA), and their practical implications for the health sector in aid-recipient countries. Design/methods: The study draws on (i) a critical analysis of the two declarations, (ii) a review of the literature on their implementation and (iii) interviews of people in charge of implementing them – both donors and government representatives. Results: The PD and AAA both have a "missing link" between, on the one hand, international cooperation policies (five pillars of the PD) and national development (health) plans; and, on the other hand, the operational level that is supposed to deliver results. They presume that by changing aid management and respecting a few principles, development results will automatically improve as through a "black box". The influence of international and national policies over health systems, service providers’ behaviour and health impacts is not treated at all by the agenda for aid effectiveness, while it is crucial for its success. Moreover, that agenda is mostly dealt with at a too high level (international forums or at best national sector level), thus deepening the disconnexion from field realities. Conclusions/policy implications: This "missing link" entails the risk that, if the "black box" does not perform as expected – that is, if health systems and health service providers’ behaviour do not evolve in a positive way – and health impacts do not improve, the aid effectiveness agenda may be rejected at all, notwithstanding its (incomplete) added value. Hence the need to closely monitor the processes of national health plans implementation, so in order to better understand how these processes are translated on the field and what could be done to ensure that health service delivery and health results ultimately improve.

Distorted segregation of DNA markers is commonly encountered, especially in inter-specific crosses. Our main objective in this study was to identify chromosomal regions consistently associated with segregation distortion in [(G. hirsutum x G. raimondii) x G. sturtianum] (HRS) hybrid. Segregation distortion skews the genotypic frequencies from their Mendelian expectations. In HRS progeny, chi square analysis (P < 0.01) showed significant skewed in all targeted linkage groups c2-c14, c3-c17, and c6-c25. Chromosomal region was regarded as being associated with skewed segregation, if three or more closely linked markers exhibited significant segregation distortion in one or more population(s). The targeted introgression regions in the tested population seem to be favourable for segregation distortion. Segregation distortion in HRS hybrid progenies differed in male and female gametes. Furthermore, the data indicated that the environment has strongly influenced the transfer of SSR markers through microspores. The consistent location of these chromosomal regions in selfed and backcross of HRS derivatives indicate probably the identification of segregation distortion regions (SDRs) in HRS hybrid. Comparison with results regarding the segregation distortion regions obtained in previous research by other authors and results we obtained regarding the absence of recombinations between BNL3436 and BNL1153 markers mapped on c6-c25 chromosome and spanned by 64 cM on the G. hirsutum map, after several generations of selfing, arise the question of the conservation of the gene order and spacing in G. sturtianum. Results showed that three SSR markers mapped on c6-c25 linkages groups were systematically transmitted in all selected progenies of the HRS tri-specific hybrid. Furthermore, the high percentages of loci with significant segregation distortion observed in this study suppose that a genetic mechanism may exist for preferential transmission of alien chromosomes segments. High heterozygosity frequencies (+/- 80%) were observed for all conserved G. sturtianum SSR markers, after several generations of backcrossing and selfing, which indicate that the cytogenetic and genetic conditions for obtaining homozygotes at high frequency are not met.
